Abstract
Light-emitting devices that include a scattering element of arbitrary shape and processes for fabrication thereof are described. In one aspect a method for forming a light-emitting device includes providing a light-emitting element (LEE) on a base surface of a base substrate; coupling a first optical element with the base surface of the base substrate, where the first optical element has a first surface facing the LEE and a second surface opposing the first surface; disposing the first optical element in a curable or settable fluid so that the fluid conforms to the second surface; and curing or setting the fluid to form a second optical element including a molded transparent layer adjacent the second surface of the first optical element.
